1. A ventilation system for an interior room, the ventilation system comprising:
a first air suction device and a second air suction device;
a suction volume control device comprising a first airflow throttling unit, a second airflow throttling unit, and a third airflow throttling unit;
a first air conduction pipe and a second air conduction pipe;
a central air conduction pipe, the first air conduction pipe and the second air conduction pipe being connected to the central air conduction pipe and adapted to provide the airflow to the central air conduction pipe;
a vacuum generating device; and
a control unit;
wherein the first air suction device is assignable to a first suction volume, and the second air suction device is assignable to a second suction volume,
wherein the first airflow throttling unit is assigned to the first air conduction pipe and is adapted to throttle an airflow through the first air conduction pipe by increasing or decreasing a cross-section of the first air conduction pipe,
wherein the second airflow throttling unit is assigned to the second air conduction pipe and is adapted to throttle an airflow through the second air conduction pipe by increasing or decreasing a cross-section of the second air conduction pipe,
wherein the third airflow throttling unit is adapted to throttle an airflow in the central air conduction pipe by increasing or decreasing a cross-section of the third air conduction pipe,
wherein the vacuum generating device is adapted to generate negative pressure in the first air conduction pipe and in the second air conduction pipe so that the first suction volume can be removed via the first air suction device by suction, and the second suction volume can be removed via the second air suction device by suction;
wherein the vacuum generating device is adapted to generate negative pressure in the central air conduction pipe so that in the first air conduction pipe and in the second air conduction pipe negative pressure is generated,
wherein the control unit is adapted to control the suction volume control device so that the airflow from the first air suction device to the first air conduction pipe is controllable,
wherein the control unit is adapted to control the suction volume control device such that the airflow from the second air suction device to the second air conduction pipe is controllable,
wherein the control unit is configured to adjust the ratio of the air volume flow in the first air conduction pipe and the second air conduction pipe as well as the sum of the air volume flows by controlling the first throttling unit, the second throttling unit, and the third throttling unit,
wherein the control unit is configured to instruct the vacuum generating device to increase the negative pressure in case the maximum size of the cross section of the opening of the third throttling unit is achieved, and
wherein the control unit is configured to control the air volume flow in first, second and third levels by controlling one or more of the first and second air suction devices, the first, second and third airflow throttle units, the sum of the air volume flows of the first and second air conduction pipes and the air volume flow of the central air conduction pipe.
